Engineering Services

The 45,700 engineering services firms in the US provide evaluation, investigation, planning, design, and development services related to utilities, structures, buildings, machines, equipment, processes, or systems. Specialty areas include civil, mechanical, industrial, electrical, electronics, computer hardware, aerospace, environmental, chemical, health and safety, materials, petroleum, nuclear, and biomedical engineering. Firms work on specific projects for clients and must be adept at project planning and management.

Dependence on Highly Skilled Personnel

Engineering service firms rely on a highly-educated, professional workforce.

Liability

Work site hazards and the complexity and scale of engineering projects expose engineering services firms to liability.

Aug 23, 2026 - Design Firms' Proposal Activity Remained Solid in Q2

• Engineering News-Record reports that, according to a recent report by consulting firm PSMJ Resources, architecture and engineering proposal activity remained positive in the second quarter, even as slowing backlogs and weaker construction spending clouded the outlook. PSMJ Resources' proposal index rose to +23.4, with all 11 markets positive and energy and utilities, water and wastewater, and heavy industry leading. However, the US Census Bureau reported that total construction spending fell 3.2% year over year in June, including a 4.7% decline in private nonresidential work, while public spending rose just 1.7%. PSMJ also found median backlog growth slowed to 5% from 11.1%. Energy remained a relatively bright spot, supported by power generation and battery storage. Despite softer backlogs, design firms reported record median operating margins, higher labor costs, increased staff, and gains in revenue and profit per employee.
• According to FMI's third-quarter 2026 North American Engineering and Construction Outlook, US construction spending on nonbuilding structures is forecast to grow 2% in 2026. Conservation and development spending is expected to lead growth at 13%, supported by the US Army Corps of Engineers' $10.4 billion fiscal 2026 civil works appropriation. Power spending is projected to rise 2% as data center demand drives utility investment, although equipment and connection constraints limit near-term growth. Highway and street spending is forecast to increase 2%, supported by committed Infrastructure Investment and Jobs Act funding. Sewage and waste disposal spending is expected to rise 2%, while water supply spending increases 1%, with data centers and advanced manufacturing supporting long-term water demand. Total nonbuilding structures spending is forecast to increase 5% in 2027, 9% in 2028, 9% in 2029, and 8% in 2030.
• Construction Dive reports that the Federal Railroad Administration will distribute $5.3 billion for passenger rail projects in 23 states, including grade-crossing improvements, track upgrades, bridge construction, and Amtrak equipment purchases. The funding, authorized by the 2021 Infrastructure Investment and Jobs Act, includes about $2 billion that had been previously designated for California's high-speed rail project after the Trump administration withdrew federal support. Projects will close more than 30 grade crossings and upgrade more than 1,000 others, with major awards going to Florida, North Carolina, Texas, Ohio, Louisiana, and Nebraska. Engineering services firms could benefit from increased demand for planning, design, structural engineering, safety analysis, and project assessment work tied to these federally funded improvements. The FRA received 103 eligible applications requesting about $11.7 billion, indicating that demand exceeded available funding.
• House and Senate committees unanimously advanced separate versions of the 2026 Water Resources Development Act, which authorizes Army Corps of Engineers projects involving ports, waterways, dredging, flood control, and other infrastructure, according to Engineering News-Record. Lawmakers could hold floor votes before the August recess, although differences between the bills would require reconciliation. The Senate version would authorize $16.5 billion for drinking water state revolving funds, $14 billion for clean water funds, and $260 million for federal infrastructure financing from 2027 through 2030. Both bills would expand alternative project delivery methods, increase participation by nonfederal entities, and encourage multiyear contracts. Additional provisions address private-sector dredging vessels, microplastics research, and grants for the rehabilitation of high-hazard dams. Supporters say the legislation could accelerate projects, reduce costs, strengthen water systems, and ease affordability pressures on utilities and customers.
